Test ID FP5PC Pyridoxal 5-phosphate (CSF)
Special Instructions
Method Name
HPLC/Electrochemistry/Fluorescence
Reporting Name
Pyridoxal 5-phosphate Conc., CSFSpecimen Type
CSFShipping Instructions
Ship samples frozen on dry ice
Specimen Required
Medical Neurogenetics collection kit (MCL T657) required.
NOTE:
One set of tubes is required per patient.
Total CSF volume required is 4.5 milliliters
Each collection kit contains 5 micro centrifuge tubes.
Tube #3 contains antioxidants necessary to perform this test.
COLLECTION PROTOCOL:
CSF should be collected from the first drop into the tubes in the numbered order.
1) Fill each tube to the marked line with the required volumes.
Tube 1: 0.5 mL
Tube 2: 1.0 mL
Tube 3: 1.0 mL (contains antioxidants necessary to protect the sample integrity)
Tube 4: 1.0 mL
Tube 5: 1.0 mL
- If sample's not blood contaminated, the tubes should be placed on dry ice at bedside
- If sample's are blood contaminated, the tubes should immediately be centrifuged (prior to freezing) and the clear CSF transferred to new similarly labeled tubes, then frozen
- Store samples at -80 until they can be shipped
2) Complete Medical Neurogenetics, LLC request form.
Include test required, sample date and date of birth.
3) Label tubes with patient name and ID number, leaving the tube number viewable.
4) Place samples inside a specimen transport bag and the Medical Neurogenetics, LLC request form inside the pouch of the transport bag.
5) Ship samples frozen on dry ice.
